Fall armyworm damage has not yet been reported in Nebraska's eastern districts, which are frequently affected. Farmers are advised, nonetheless, to use caution. These caterpillars migrate from the south and are easily recognized by their unique body markings and an inverted "Y" on their heads. Once they reach ¾ inch in length, they can cause significant damage to crop such as alfalfa and newly sowed cereals.
It is advised to do scouting in the early morning or late afternoon to find infestations early on. Treatments are advised if three or more caterpillars are identified per square foot.
Concurrently, pasture management becomes crucial as summer ends. Common weeds like sunflowers and kochia become more visible, especially in overgrazed or thin grass areas. While immediate spraying is ineffective on mature weeds, a strategic approach involving enhanced grazing management and targeted herbicide applications in spring can provide long-term relief and prevent future outbreaks.
Additionally, with the corn silage harvest underway, proper timing and technique are vital. Ideal silage should have 65-70% moisture content for optimal fermentation and nutrient retention. Assessing the milk line on corn kernels helps determine the best harvest time to maximize starch content and overall feed quality.
Farmers are encouraged to integrate these practices to maintain healthy crops and pastures, ensuring sustainability and productivity in their agricultural endeavors.
